Highlights

  • X-Men are missing from the Marvel Cinematic Universe (MCU) and one theory suggests Professor X hid the mutants using his telepathic powers.
  • The theory proposes that the mutants were hidden due to increased mutant births and human-on-mutant crimes.
  • The acquisition of 20th Century Fox by Disney paved the way for a potential crossover between the Avengers and X-Men in the MCU.

X-Men are noticeably missing in the Marvel Cinematic Universe (MCU), and one theory suggests that Charles Xavier, aka Professor X, has something to do with it.

X-Men and Avengers exist in the same universe in Marvel Comics. However, the mutants are missing in the Marvel Cinematic Universe (MCU), which features the Avengers like Captain America, Iron Man, and Thor. One possible reason was that X-Men and Avengers used to exist in separate film franchises owned by different studios, but one fan theory suggests a reasonable but "horrific" explanation.

X-Men Villain Fanart Shows Live-Action Casting That Never Made It To Screen

An X-Men villain makes their long-awaited live-action in fan art that imagines the character's scrapped appearance in one Marvel movie.

Reddit user Acceptable Quail 357 suggested Professor X hid the mutants using his telepathic powers. X-Men was considered a superhero team before mutants became rampant and terrible things happened. The user admitted he wasn't sold on the idea because the arc seemingly suggested that Professor X "abandoned the dream." The user wondered what made the powerful mutant give up and keep his kind hidden. Additionally, considering their potential, powerful mutants like Magneto are unlikely to agree to be hidden.

The post included a document mentioning mutant extinction events. There was reportedly an increased number of mutant births, which opened the door for human-on-mutant crimes to be enacted. It also included names who reportedly committed major mutant crimes, including Steven Lang, Mister Clean, Graydon Creed, Cameron Hodge, Wanda Maximoff, and Bolivar Trask. Elizabeth Olsen's Wanda Maximoff, a.k.a. Scarlet Witch, was featured in multiple Avengers movies. She also scored her spinoff series, WandaVision, which streams on Disney Plus.

The theory opened doors to more speculations about the X-Men's fate in the MCU. While many didn't like the fan theory, it was somehow a good arc to explain the absence of the mutants in MCU, which is difficult to bring up. In the comics, X-Men and Avengers frequently come into contact and are sometimes allied or in conflict. There was even a storyline titled "AvX," where the two groups were pitted against each other. The only potential reason they didn't appear on the screen together was because Marvel Studios previously did not own X-Men. Fans also noticed a mistake involving Iman Vellani Ms Marvel in The Marvels that was seemingly tied to this issue. One scene featured her profile from SABER, and her heritage was marked "Inhuman" and she was classified as "polymorph" despite being written as a mutant in the MCU, so fans wondered why. The possible reason was that, at the time, Marvel Studios did not own X-Men, so the comics made Ms. Marvel an Inhuman. However, it got the rights to the franchise featuring the mutant superheroes when Disney acquired 20th Century Fox, making Ms. Marvel the first official mutant in the MCU.

With Marvel Studios owning both Avengers and X-Men, fans can expect a crossover soon. And with Secret Wars coming up, both worlds might eventually merge into one, and the long-awaited reunion of the mutants and superheroes would likely be featured on the big screen. There is a chance this will happen soon, as an X-Men MCU reboot is already in the works. However, not all characters will appear in Marvel Studios' version because the powerful mutant supervillain Magneto will allegedly be replaced with the antihero, Mister Sinister.

The X-Men films are available on Disney Plus.
